AUTOMATIC ELECTRIC WATER-PURIFIER.

Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed December 28, 1915. Serial No. 69,111.

To all whom it may concern:

Be it known that I, GUs'rAv EMANUEL ERIoKsoN, a subject of the King of Sweden, and a resident of 451 Ninth street, in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Automatic Electric Water- Purifiers, of which the following is a specification.

The purpose of this invention is to provide an electric water sterilizer and filter which will purify water flowing at full pressure.

One advantage of this invention is to provide an apparatus of this class which is very compact and at the same time highly efiicient.

Another advantage is to provide an apparatus of this class which can be readily taken apart for inspection.

Another advantage is to provide in conjunction with an apparatus of this class a signal to show that current is flowing when the water has been turned on.

Another advantage is to provide in conjunction with an apparatus of this class a filter directly secured to the face of the apparatus.

Another advantage is to provide in conjunction with an apparatus of this class a switch directly secured to the rear face of the apparatus, operated by the valve handle which controls the water supply.

Another advantage is to provide an apparatus of this class which is entirely sanitary, and attractive in appearance.

Another advantage is to provide an apparatus of this class wherein the possibility of shocking the operator has been eliminated.

Another advantage is to provide an apparatus of this class which is mainly sup ported by the inlet pipe.

Further advantages and possibilities will become apparent as the specification pro- ,ceeds.

a front view of the casing 2 of Fig. 2, with cover 3 removed, disclosing plate 35. Fig. 4 is a view of the vertical cross section of Fig. 1 through the center. Fig. 5 is av rear view of Fig. 3 disclosing the switch box 13 and mechanism within. Fig. 6 is a view of the active side of plate 34 of Fig. 4.

It is a well established fact that water when properly exposed to action of an electric current will lose all of its microbe and bacterial content by decomposition and have its impurities rendered fiocculent or ourdled, making the removal of these impurities then comparatively easy by filtering. Experience has shown that aluminum electrodes are among the most practical for the purpose, and hence the employment of such in the form of grooved plates, 34 and 35, either cast or struck from sheets of the metal.

It has been found convenient to have the filter 5 cast in one piece with the cover 3. The main body or casing 2 of the apparatus is made of any dielectric substance suitable for the purpose, such as porcelain, glass, hard rubber or insulating composition. Porcelain is preferred, owing to its sanitary appearance and condition as well as economy in price.

A switch box 13 is attached to the rear of easing 2, thereby adding directly to the utilitv of the apparatus and utilizing space that would otherwise be waste.

A signal in the form of a light 1 has been found useful in signaling the presence of electric current in the apparatus when water is flowing through the same, and in calling attention when the water has been left flow Tteferring to the drawings, the operation and construction of the apparatus are as follows:

Water arrives from the mains in pipes 48 of Fig. 4 where it may be tapped from faucet 46 in its ordinary state, It will otherwise fiow up through the T elbow 47 and pipe 20 into chamber 44 in valve 19 when the cylinder 43 is turned clockwlse by pushing back the handle 8 shown in Figs. land :2." The water continues upward through P ne 22 and in. through aperture 23 in ca ing 2 and thence up between the convolu tions of aluminum plates 34 and 35. Plate 35 is secured in place by two screws and 38.

Screw 30 is capped with a flat contact in the switch box 13, shown also in Fig. 5. Plate 34 rests with flange 2 in Fig. 5 upon the depressed shoulder 2 of casing in F ig.

shown also in Fig. 6. V e

lVhen handle 8 of Figs. 1 and 2 is pushed as stated extension 21 draws down vertical link 9 and the horizontal arm 12 connected thereto by bolt 11, arm 12 descending vertically in slot 10, then Figs. 4 and 6, portions 49 and 53 of plate12, 49 and 53 move down in guides 50 and 54, and the contact head on the extreme right of rod 52 passes the lump on contact plate 40, and by virtue of the spring mounted on rod 52- exerts a pressure sufficient to swing dielectric switch bar 42 anticlockwise about center bolt 29 to connect by means of metallic forks 41 and 51 contacts 31 with 32, and 30 with 39, Bar 32' connects with charged wire 15, and bar 39 connects with another wire 15, both wires passing upward through collar 14 and being connected to a plug 16 of Fig. 1.

Returning to Figs. 4 and 6, the water from inlet 23 passes upward between the grooved plates 34 and 35, the ridges 28 of plate 34 as shown in Fig. 5 extending when in position as shown in Fig. 3 partly into grooves 24 of plate 35 and vice versa. Between the plates-the water is now traversed by the electric current which curdles the suspended and dissolved impurities to practical completion by the time the water reaches aperture 33. Thence, it continues through fiber disk 26 and cover 3 into chamber 4 of hood 4, whence it descends through the cotton stuffed in chamber 5 of the filter 5. Seeping through the cotton, the water loses all suspended contentand proceeds down through perforated filter plate 45 in bottom cap 17, and out through spout 18.

The cover 3 is preferably cast-in one piece with hood 4 and filter 5, and is secured to the porcelain body 2 by means of wing. nuts on bolts 7-, 7 being four in number, as shown in. Figs. 1 and 2, the holes in body 2 for the same being shown in Fig. 3 where one hole is noted 7 The bolts 7, 7 in Fig. 1, and 7 in Fig. 2 are'shown in arearfview cover 3, a groove 6 as also shown in Fig.

3 is -occupied by a rubber gasket 6., a corresponding groove existing in the cover 3.

In Figs. 4 and 6 are shown bolt 38 which interiorly secures plate 35 in position and connects the samewith exterior strip 37 the latter extending down into socket 1 and connecting with light 1. In Fig. 6 is shown the hole 26 wherein is located-the bolt 26' of Fig; 4, the inner hooked end contacts ingwith the. flange of plate 34, the point- 0t contact on the flange being noted as 26 in Fig. 5. The. outer end of bolt 26 connects with strip 8., the latter contacting with the side of socket 1 and thus with light 1. This results in having the light connected to the plates and parallel with them, but entirely dependent upon them for source of current. Thus, if thecurrent for any reason should fail to reach. plates 34 and 35 when the valve 19-isopenedlby handle 8,the light would also fail to register a signal, show v ing instantly-that something was wrong and needed immediate attention.

Having thus fully described my invention,
